Resettable fuses for overcurrent protection in photovoltaic solar array systems
Journal Title: Journal of Physics and Electronics - Year 2018, Vol 26, Issue 2
Abstract
The general scheme of using self-repairing PolySwitch-type fuses to limit the current in photovoltaic systems of solar arrays and the resulting requirements for their parameters are analyzed. The possibilities of applying modern serial resettable fuses for solving the problem of increasing the reliability of solar panels are studied. In particular, it is established that currently available nomenclature of fuses of the PolySwitch type allows implementing protection of photovoltaic systems of solar arrays against current overloads at the level of photovoltaic modules. At the same time, for the implementation of such protection at the level of solar cells, it is necessary to develop fuses with lower values of electrical resistance in the conducting state and lower tripping currents.
